CHICAGO -- There’s little doubt the biggest area of concern for the Chicago Cubs last season was depth within their starting rotation. They just didn’t have any. Fortunately, it didn’t come back to bite them as their rotation remained relatively healthy with their top four starters making every start in 2015. But when several pitchers -- namely Jason Hammel -- faltered down the stretch, the Cubs didn’t have anywhere else to turn. That’s not an exaggeration. The organization simply didn’t have huge trust in its Triple-A choices nor could it find much in the marketplace.
